LOCOMOTIVE DRAW-BAR.

SPECIFICATION forming part of Letters Patent No. 386,888, dated July 31,1888.

Application filed October 15, 1887. Serial No. 252,475.

To all whom it may concern:

Be it known that I, HORACE WV. LoUNs- BERY, a citizen of the UnitedStates, residing at Corning, in the county of Steuben and State of NewYork, have invented certain new and useful Improvements in LocomotiveDraw- Bars, of which the following is a specification.

My invention relates to draw-bars for connecting the engine orlocomotive to the tank or tender. Oustomarily the wear and strain onsuch draw-bars lengthens the connection between the engine and the tankto such an extent that from time to time the draw-bar has to be heatedand upset by hammering to reduce it to such length that the tank andengine will be in the required close connection. Heretofore otherdevicessuch as springs and wedges-have been employed for taking up wearin this case, without, however, practical success.

My improvement consists in a draw-bar provided with an eccentric soarranged as to render possible the shortening of the connection betweenthe engine and the tender at will.

The invention further consists in the peculiar construction andarrangement of the eccentric, as will be hereinafter more fullydescribed.

In the accompanying drawings,FigureIrepresents in plan my improveddraw-bar. Fig. II is a vertical sectional view of the same. Fig. III isa bottom plan view thereof. Fig. 1V is a plan view showing a modifiedform having an eccentric at each end.

1 may represent the draw-bar. As shown in Fig. I, this draw has at oneend the customary eye, 2, for connection with either the engine or thetank, and at the other end has a larger eye, which receives a disk, 3,having an eccentric eye, 4, to receive the pin for connecting this endof the draw-bar to either the tank or the engine. The disk 3 has aflange, 5, on one side, and it rests upon this flange when in positionin the draw-bar. On the other side of the disk 8 is a tongue, 6, whichretains the disk in position by bearing upon the under side of thedraw-bar. A notch, 7, is provided in the drawbar to allow the pas- (Nomodel.)

sage of this tongue when the disk is being placed initsseat. After thetongue has passed through this notch, the disk may be turned so as tobring the tongue beyond the notch under the draw-bar, and thus preventaccidental dislodgment of the disk.

The flange 5 has a series of notches, 8, any one of which may receivethe headed pin 9, which may be placed therein and passed through thenotch 7. When thus in position, the headed pin 9 is held in position bythe split key 10. If desired, two pins 9 may be used, the notch 7 beingin such case duplicated.

In Fig. I the disk is so arranged that the eyes 2 and 4 will be at theirgreatest distance asunder. Vhen wear occurs, the eyes are brought nearertogether by turning the disk in the direction of the arrow, the pin 9being first removed and subsequently placed in the desired notch forholding the disk at the necessary point.

In Fig. IV, I have shown substituted for the customary eye, 2, a disksimilar to that on the other end of the draw-bar, so that,if necessary,adjustment can be made at both ends.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In combination with a draw-bar having an eye, the latter having anotch at one side, a disk situated in said eye and having an eccentriceye and a peripherally-notched flange, and a pin adapted to occupy thenotch at one side of the first-mentioned eye and one of the notches insaid flange, substantially as and for the purpose set forth.

2. In combination with a draw-bar having an eye, the latter having anotch at one side, a disk having an eye, a peripherally-notched flangeat one side of said disk and a tongue at the other, adapted to passthrough said notch, and a pin adapted to occupy the latter and one ofthe notches in said flange, substantially as set forth.

3. The combination of the draw-bar having an enlarged eye at one end, adisk situated in said eye and having an eccentric eye and a flange, thelatter having notches on its pcof said notches and having a seat in thedrawsaid notch, substantially as and for the purbar, and a split keyfitting in one end of said pose set forth.

pin, substantially as shown and described. HORACE W. LOUNSBERY.
